The part offers two channels on each side of the isolation barrier (2/2 input configuration), all unidirectional, running at a maximum data rate of 1Mbps. Propagation delay is 100ns max, with pulse-width distortion held to 40ns — tight enough for most SPI and UART isolation applications at this speed grade. Common-mode transient immunity is rated at a minimum 25kV/µs, which keeps the data path clean when switching noise couples across the barrier in a motor-drive or flyback converter environment. The 2500Vrms isolation voltage is the working spec for basic insulation in 48V to 400V systems — it covers most automotive auxiliary inverters, on-board chargers, and industrial sensor interfaces. If your design requires reinforced insulation or a higher working voltage (e.g., 3750Vrms or 5000Vrms), you would step up to the ADUM1310 or ADUM1411 series siblings. The 1Mbps data rate is a deliberate choice: it is fast enough for isolated SPI at moderate clock rates, UART up to 115200 baud, and general-purpose GPIO isolation, but slower than the 10Mbps and 90Mbps variants in the same package. If your bus needs higher throughput, look at the ADUM1402WCRWZ (the 'C' suffix indicates a higher speed grade) — the pinout and footprint are identical, so a BOM swap is possible without a board respin. Supply voltage spans 3V to 5.5V on both sides, so the part works directly with 3.3V or 5V logic without a separate level shifter. The answer to the common question 'Can ADUM1402WSRWZ work at 5V supply?' is yes — it is rated for the full range, and the 5V rail gives you the best noise margin on the propagation delay spec. ## Package and rework considerations Housed in a 16-SOIC wide-body (0.295-inch, 7.50mm width) package, the ADUM1402WSRWZ is a standard surface-mount part that reworks cleanly with hot air. The wide-body SOIC gives good clearance for under-pin inspection and is less prone to tombstoning than the narrow-body variant. No exposed thermal pad, so the reflow profile is the standard lead-free ramp: prebake at 125°C if the moisture barrier bag has been open past the floor-life window (MSL 3). ## Lifecycle and sourcing For dual-sourcing resilience, the closest functional second-source candidate is the ADUM1310ARWZ (3-channel, same 2500Vrms and 1Mbps), though the channel count differs. If you need a drop-in 4-channel alternate with the same pinout, the ADUM1411ARWZ-RL is a 3/1 input-configuration sibling worth evaluating.","metaTitle":"ADUM1402WSRWZ Digital Isolator, 2500Vrms, 1Mbps","metaDescription":"ADUM1402WSRWZ from Analog Devices: 4-channel digital isolator, 2500Vrms isolation, 1Mbps data rate, automotive grade (-40°C to 125°C), 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tube","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"40ns","Propagation Delay tpLH / tpHL (Max)":"100ns, 100ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.41","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.41000","currency":"USD"},{"qty":10,"price":"$7.60000","currency":"USD"},{"qty":25,"price":"$7.24680","currency":"USD"},{"qty":100,"price":"$6.29230","currency":"USD"},{"qty":250,"price":"$6.00952","currency":"USD"},{"qty":500,"price":"$5.47924","currency":"USD"},{"qty":1000,"price":"$4.77225","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1ede0b49820924dd19648c8b0dbeca5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM1402WSRWZ and ADUM1402WCRWZ?","answer":"The primary difference is the data rate: the ADUM1402WSRWZ is rated for 1Mbps, while the 'C' suffix variant (ADUM1402WCRWZ) supports a higher speed grade, typically 10Mbps or 90Mbps depending on the specific suffix. Both share the same 16-SOIC wide-body package and pinout, so a BOM swap is possible without a board layout change."},{"question":"What is the closest functional equivalent to ADUM1402WSRWZ?","answer":"The closest functional second-source candidate is the ADUM1310ARWZ, which is also a 1Mbps, 2500Vrms-rated digital isolator in the iCoupler family, but it has 3 channels (3/0 input configuration) versus the 4 channels (2/2) of the ADUM1402WSRWZ.
